本研究探讨驾驶员在与车内系统互动时，驾驶员的眼动与其驾驶表现之间的关系。在41名受试者（29名男性和12名女性）的道路试验中，使用一辆装有仪表的车辆，研究了一组车内视觉任务（VT）对驾驶员工作负荷、任务绩效和眼动的影响。根据两组选定的驾驶员眼动参数，通过聚类分析将注意力分散程度分为三组。结果表明，车载VT对驾驶性能有负面影响，并伴随着驾驶员视觉行为的变化，包括速度降低、速度偏差增大和转向行为不可预测。与此同时，向前看的减少被观看触摸屏所取代，并且随着任务难度的增加，观察到驾驶员的眼跳显着增加。受室性心动过速影响最大的组表现出明显更差的驾驶性能。因此，可以得出结论，由分心引起的性能恶化可以通过视觉行为变化进行诊断，并且可以使用眼动来监测驾驶性能的变化。
This study investigates the relationship between drivers' eye movements and their driving performance, when drivers interact with in-vehicle systems. The impact of a set of in-vehicle visual tasks (VT) on drivers' workload, task performance and eye movements was studied in an on-road experiment with 41 subjects (29 male and 12 female), using an instrumented vehicle. The degree of distraction was differentiated into three groups by cluster analysis based on two sets of selected drivers' eye movement parameters. The results showed that the in-vehicle VT had a negative effect on driving performance, accompanied by a change in drivers' visual behaviour, including a reduction in speed, a higher speed deviation and less predictable steering behaviour. At the same time, a decrease of looking ahead was replaced by viewing the touch screen, and a significant increase in drivers' saccade was observed as the task difficulty level increased. The groups that were the most significantly affected by VT demonstrated a significantly worse driving performance. It is therefore concluded that the deteriorated performance caused by distraction can be diagnosed by visual behaviour change, and it is possible to use eye movements to monitor the change in driving performance.
